Claims. (01. 132- 36) This invention relates generally to machines such as are utilized in beauty parlors for the commercial waving of human hair. i

In the past machines for the'waving of human {5 hair have commonly utilized an overhead canopy, which serves to suspend a plurality of electrical heaters.- This canopy inturn is supported by a portable'pedestal or stand. The difficulty with machinesof "this 'type is that they occupy considerable room when not in use, and are relatively unsightly. It is an object of the present invention to provide a hair waving machine which can be collapsed into a neat appearing compact structure, when not in use.

A'further'object of the invention is to provide I a hair waving machine which can be more readily manipulated byan operator, and which can be more conveniently controlled to secure the desiredwaving efiect. Further objects of the invention will appear from the following description in which a practical embodiment of the invention has been set forth in detailin conjunction with the accompanying drawings. It will be understood that the appended claims are to be accorded a range of equivalents consistent with the state of the prior art.

Referring to the drawings: Figure l is a perspective view, illustrating my 3 0machine with its-operating parts extended in condition for use.- p r Fig. 2 'is a side elevationalviewlikewise showing the operating parts of the machine extended, and indicating the manner-inwhichthese parts are collapsed'whenthe machine is 'not -in use. i Fig. 3is" a'c'ross sectional detail taken along the-line 3-3 of Fig. 2. i

Referring first'to R A machine consists generallyof a base structure 10, preferably in the form of a cabinet. Secured 0 to the top of cabinet 10, there is a box-like V V v H e 5 lug 2'7. Lugs 2'7 are eachcarried by a'isliding structure 11, which as will be presently explained, may serve to house certain parts of the machine when in' collapsed position. The boxlike structure 11 is hingedly connected to the F cabinet 10 as by means of piVotalconnectionslZ,

so that itcan be swung to either a vertical pqsi- 3 tion as shown in Fig. l, or to a horizontal posi; tion overlying the top .of the cabinet, as ShQWI in Fig. 4. By means of a conventional brace 13, structure 11 canbe releasably locked in its verg tical position.

The box-like structure .11 serves as, a support for another structure 14, which j in turn adapted to suspend electrical hair waving heaters 16. As will beqpresently.explained,,certain'me chanical elements so connect Structures 11 and 1 that the ru ture ay. ith e' uiiported in the position illustrated in Fig. i or in a collapsed position within the "s ructura -While the details of structure 114' very in p actice, I have founditsatisfa y t'o inakef it tan gular in contour, as ill fstraite d more in Fig. 5." As illustrated it isf'a hollow'hous g made of asuitable insulating material such as a molded phenolic condensate product; "Its outer and inner peripheries are apertured, and its "in terior serves to houseelectrical'contators-and conductorsto provide a plurality of ectifical outlets. As a suitable manner in which-to sillspend theelectricalheaters l6 rrdmistr'iicmre n, I 'I have shown each heater connected to a flexible electric cord 18, which in turn is corinecte d to'a cord 18 is frictionally engaged t' plug 119', to permit limited vertical adjustmentof the heater.

. u a b a' hab a li 1 str d j 14, to makelthe necessaryjelectrical connections, and to support the heaters in proper operating position. The nu'mb'er 'of heaters je mp loyedi'cafn of coursebe varied to suit different ieq li leiiients.

The elements which servefto connect struc-fu tures" 11 and,l4fiareprefera 1y i d, as" :0 lo wsz -ffigke 2, formed of 1a 'm taltubeor ar, hasfits' m e 'dns z, ta ls' hinsed y nett to he stru j u1. 1 more many in Fig. 3, eachside QpcrtionQZ'B of Z}- y k'c 2 1S P dd wi p t 9W bn 2, to a vertical wall 24' fixed fwithin structur '11.

Thus theaxisoi the pivo a m vement or 926 22 with respect to structure 11 is hqrizon and is parallel to the pivotal axis ofistructure'll 1 rod28, one'jend of provid ed'fwlth"a' n outer knob29; Compression spring' '31 se v's'to j urge rod 28 in one direction, thus' serving' to maintain iug" 27 in locked position with respect h a shown to flange 26, until released by pulling outwardly upon knob 29.

Journaled to the intermediate and horizontal portion 33 of yoke 22, there is a sleeve 34. Fixed to sleeve 34, there is a pair of spaced parallel rods or arms 36. Swinging movement of arms 36 with respect to yoke 22 is limited, as by means of pins .37 fixed to yoke 22, which are accommodated within segmental recesses 38 formedin the ends of sleeve 34. The amount of swinging movement thus permitted should be at least about of a circle, or through the are indicated in Fig. 2. The connection between arms 36 and structure 14 is preferably a sliding one, to permit this structure to be slid to a position relatively close to sleeve 34 before the collapsing operation to be presently explained. Arms 36' are provided with enlarged heads 41, to prevent disengagement of this sliding connection.

Before describing the manner in which my machine may be collapsed and extended in an operating position, certain features ofthe boxlike structure 11 must be described in greater detail; The side wall 42, which is uppermost when structure 11 is in a horizontal position as viewed in Fig. 4, is-provided with a hinge connection 43 with the main body of structure 11.

Likewise the wall 40 of structure 11, which forms the front wall as viewed in Fig. 4, is provided with slots 43a to accommodate the portions 23 of yoke 22. The wall 44, which forms the bottom of structure '11 as. viewed in Fig. 4, or the front of the structure as viewed in Fig. 1, preferably forms an instrumentpanel for switches or other control devices utilized inoperating the machine. Thus as shown in Fig. 1, mounted upon wall 44 are the electrical'switches 46, and the control device 47, which may be a time control switch.

Operation of my machine can bedescribed briefly as followsz-While the machine is in operation its parts are positioned substantially '34 upon yoke 22, structure 14 swings relative to the yoke, so that when yoke 22 is in its lowermost position and withinstructure 11, structure 14 can be swung upwardly and inwardly into structure '11, between the portions 23' of the yoke. It is of course evident that when the parts are being swung into structure 11, wall 42 is in ahorizontal or open position. Thereafter wall '42, is swung, to .closed position, and then structure 11 is swung down tohorizontal position as shown in Fig; 4. In replacing, the machine in position for a waving operation, substantially the same "operations are followed in reverse order, except automatically locked in extended within thestructure 11. It is of course evident thatstructure 11 can be made of sufficient dimensions that it can house all of the heaters required in a permanent waving operation.

' When extended, the controls on panel 44 are readily accessible and the top of the cabinet is also available. When collapsed the machine is neat in appearance I claim:
